We are resuming the trout surveys this year and anticipate this happening in September. The exact date is yet to be determined, but most likely will happen in the last 2 weeks of the month like we have done in the past. Simply put, an electrofishing survey is the use of an electrical current to capture fish. In most lake or pond applications an electrofishing vessel producing pulsed direct current (DC) is the best option. When performed carefully and correctly, this process temporarily stuns the fish and allows fisheries biologists to safely collect them. After the fish are netted, they are placed in an insulated livewell which keeps them safe from the electrical field until the survey is complete. Once the appropriate amount of fish are collected, data such as weight, length, species and sex can be gathered, in addition to scale or tissue samples, as needed. Electrofishing is a safe and efficient survey method that allows biologists to obtain a more comprehensive picture of the fishery in order to calculate important metrics. This data, evaluated in conjunction with water quality assessments, fish habitat, and stakeholder goals, provides fisheries biologists with the information needed to develop customized fisheries management plans.
Performing the surveys in September is optimal in that the water is low (with few exceptions), water temperature is cooler, and it gives us a good health check. Many people do not realize it, but the metrics for for the health of the trout have been excellent. And this is in September after 2-3 months of low water, prime time fishing pressure, and some of the hottest weather of the year. This emerging evidence, along with temperature surveys, largely refutes the idea that the low water conditions are entirely detrimental to the trout. Yes, the low water puts the trout at certain risks, especially by the 2-legged predators, but the fishery is thriving. It is a wild trout fishery and subject to risks all year long.
